Dominant male sterile--Marc Albertsen and M.G. NeufferMs41 and Ms*-7255, located
on chromosome 4L, are not alleles but are linked. Because Ms41 sometimes
makes small amounts of viable pollen, it was possible to cross on Ms*-7255
and obtain progeny, which when evaluated should be 1/4 double heterozygote.
These individuals should be male sterile and when crossed as female by
normal should give material which would provide a test for allelism. Such
a test was made and the results proved that the two mutants are not alleles
but are linked with 14±2cM between them. Ms*-7255 is designated
as Ms44.Please Note: Notes submitted to the Maize Genetics Cooperation
